To all whom it may concern." v I Be it known that 1, CHARLES F. FILoR, a

citizen of the United States, residing at Trenton, in the county "of Mercer and State of New Jersey, have invented new and useful Improvements in Adjustable fHandle Bars for Bicycles, of which the following is a specification.

This invention relates to improvements in bicyclesand has for an object the provision of means for securing. the handle barsto the bicycle in a manner topermit ofhor'izontal rotary: adjustment, whereby the said handle, bar's may bepositioned substantially'p'arallel; with the frame, or' maybe: novedtoa posirider. is Anotheriobject of the invention istjhe pro construction v being such; that the adj ustment ble stem of the bolt, the invention beinges pecially adapted .for use vin connection. with the usual expansiblestemj I 7 Other objects and advantages ofthe inven- 7 tion will appear as the following description is read in connection withthe ac'company ing drawings. 35

In the drawings Figure 1 is a fragmentary elevation showing the front portion of a bicycle with the invention applied thereto.

Figure 2 is a top plan view of the same and illustrating by' dotted lines the reverse 7 position of the handle bars.

Figure 3 is a view similar to Figure 2 showing another position of the handle bars.

Figure 4 is an enlarged side elevation of the handle bar stem with the handle bar shown in section.

Figure 5 is a view showing the expansibie stem and the swiveled end of its extension in section.

Figure 6 is a section 011 theline 66 of Figure 4 looking in the direction of the arrows.

Referring in detail to the drawings wherein like characters of reference denote corresponding parts, the head of the bicycle is indicated at 10'. This head may be of the- Application filed November 9, 192D...

the extension 19 is'adjustably connected to the handle bars 12 by a clamp 21, or in any other preferred manner. The lower end of the sleeve 20 rests upon a collar or flange 22 which is carried by and preferably formed integral with the stem 11, while the upper end of the said stem is provided with a reduced threaded "extension'23 which receives a nut 24. This nut-bearsupon a shoulder 25 formed at the inner end of the reduced threaded extension 23. and is of suflicient diameter to extend over the upper end of the sleeve 20, so that the said sleeve will be '2 respect to the stem but will be permitted held against longitudinal movement with -rotary movement thereon} The length of the sleeve is such as to provide a free'working fit between the collar or flange 22 and 1 Y the nut 24.

In order-to hold the sleeve against rotary movement there is provided a locking dog 26, which is mounted upon a pivot pin 27, the latter passing through openings provided in spaced cars 28 extending from and disposed longitudinally of the sleeve 20. These ears are located upon opposite sides of a groove formed in the sleeve and the dog 26 is provided with a tooth 30 which enters this groove and engages any one of a'number oi notches 81 provided in the collar or flange 22. The dog is normally forced inward so that the tooth 30 will engage these notches,'by means of a spring 32, which has one end inserted in a notch formed in the toothed end of the dog and its opposite end bearing against the bottom of the groove 29. A finger piece 33 projects downwardly from the dog 26.

By inserting the finger beneath the finger piece and lifting the dog so as to disengage the tooth 30 from the notch, the sleeve may be rotated about the stem 11 so as to position the handle bars either to the full line position shown in Figure 2, the dotted line shown in that figure, or to'the position shown in Figure 3 upon either side of the frame.

Theinvention is susceptible of various changes in its form, proportions and minor details of construction and the right is herein reserved to makesuch changes as properly 'fall within the scope of the appended claims.

Iaving described the invention What is claimed is v '1. The combination with a bicycle having an expansible handle-bar stem and an expander bolt extending longitudinally through said stem, of means for securing the handle bar to the stem in a manner to permit of horizontal rotary movement, a spring actuated locking element carried by the handle bar securing means, and means spaced around the stem for causing the locking element to operate to hold the handle bar against movement.

v 2. The combination with a bicycle having an expansible handle bar stem and an expander bolt extending through said stem, of means for securing the handle bars to thestem in a manner to permit of horizontal rotary movement only, a notched collar surrounding the stem and a dog movable with the handle bars to hold the latter against accidentalv movement;

3. The combination with a bicycle having extending longitudinally longitudinally 7.

an expansible handle bar stem and an expander bolt throughsaid stem, of a detachable. handle bar extension having an opening in one end to receive the stem, a collarcarried by and surrounding the stem for supporting the extension, means detachably secured to the extension and engageable With the extension for holding the latter against independent upward movement and means carried by the extension and engageable with the collar to I hold the extensioninadjusted position.
